Privilege Escalation in Hibernate Validator

High severity GitHub Reviewed Published Jun 15, 2020 to the GitHub Advisory Database • Updated Jan 27, 2023

Package

maven org.hibernate:hibernate-validator (Maven)

Affected versions

>= 5.2.0, <= 5.2.4.Final
>= 5.3.0, <= 5.3.5.Final
>= 5.4.0, <= 5.4.1.Final

Patched versions

5.2.5.Final
5.3.6.Final
5.4.2.Final

Description

In Hibernate Validator 5.2.x before 5.2.5.Final, 5.3.x before 5.3.6.Final, and 5.4.x before 5.4.2.Final, it was found that when the security manager's reflective permissions, which allows it to access the private members of the class, are granted to Hibernate Validator, a potential privilege escalation can occur. By allowing the calling code to access those private members without the permission an attacker may be able to validate an invalid instance and access the private member value via ConstraintViolation#getInvalidValue().

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
